The iceberg wasn’t the only culprit in the Titanic’s sinking; In this edition of “Science Xplained,” scientist Ainissa Ramirez demonstrates how the metal rivets that held the ship together became brittle in the frigid waters and broke apart on impact with the iceberg, likely contributing to the enormity of the tragedy.

AUSTIN, Texas — A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea.
The most extensive record yet of the evolution of the floating ice shelves in the eastern Amundsen Sea Embayment in West Antarctica shows that their margins, where they grip onto rocky bay walls or slower ice masses, are fracturing and retreating inland. As that grip continues to loosen, these already-thinning ice shelves will be even less able to hold back grounded ice upstream, according to glaciologists at The University of Texas at Austin’s Institute for Geophysics (UTIG).

*University of Minnesota Research Finds Sex Ratios Influence Financial Decisions*
MINNEAPOLIS / ST. PAUL — The perception that women are scarce leads men to become impulsive, save less, and increase borrowing, according to new research from the University of Minnesota’s Carlson School of Management.
“What we see in other animals is that when females are scarce, males become more competitive. They compete more for access to mates,” says Vladas Griskevicius, an assistant professor of marketing at the Carlson School and lead author of the study. “How do humans compete for access to mates? What you find across cultures is that men often do it through money, through status and through products.” (more…)
